Fear is part of most of us. Fear of speaking, of letting others down, of debt, of problems in a relationship, of death, of taxes, of succes, of failure. You name it; someone fears it.
The thing about fear is that it's usually for the future.
That fear of speaking... once you get up to the podium and start, you've started. The fear is usually what you feel BEFORE you have to speak, and you imagine all the awful things that are going to happen when you get up there.
Fear of letting others down... It's rarely as bad as we think. Sure, we do let others down sometimes; we're only human. Rarely, though, does it result in the complete and total exile we imagine. And if it does, then we usually figure out that it was for the better.
Fear of problems in relationships.... we're sure that this problem here and now is going to lead to irrevocable actions, and when it comes down to it, we usually work it out. And, like above, if it doesn't, then it's probably better that the relationship is gone anyway.
Fear of debt.... yes, you might have creditors calling you, but in most cases, they're not taking your house or your car, although your fear tells you that's exactly what will happen.
Look around you right now. You have food. You have shelter. You have a computer or smartphone with Internet access. You're probably wearing clothes and not a burlap sack. When you went to the grocery store this morning, you didn't have to dodge bullets because you don't live in a war-torn nation. Nazis aren't breaking down your door and taking you away to hell.
It doesn't mean that bad things don't happen. When they do, we stand up and do what's needed.
So, fear is really just a fear of what might happen (and rarely does).
Focus on what's around you right this minute, and tell the fear to take a hike.
